Activity C: Patterns in motion Get the Gizmo ready : Click Reset . Select No friction . Place only the soda and book on the cart. Set the Fan speed to High . Select No Friction . Question: Are there any patterns in the motion of objects? 1. Run Gizmo : Be sure No friction is selected. Click Play . After about 3 seconds, turn the fan Off .

The position of the cart is its location (how far from the start line). What pattern do you see in the position data after the fan is off?
3. Connect : How is the final speed of the cart related to the pattern in the position data?
